What matters is whether you have a full PPL or not. It doesn't even need to be current.
I was able to qualify to attend an ATPL ground school course when my hours were much older than yours and my PPL not valid for a good many years.
Incidentally, there was nothing wrong with Titanic: she was a splendid vessel and in fact more seaworthy than the Andrea Doria which was built in the fifties. Titanic was sunk by poor seamanship and the Doria had a fight with the liner Stockholm, (which just happened to have ice breaker's bows).
